Cl. 117-2 TC 4 Claims ABSTRACT OF THE DISCLOSURE A material for correcting errors of any type of indicia and particularly typewritten errors. The correction material comprises a light-transmitting base sheet upon which are provided rectangular coatings of a composition, a portion of which is readily fractured from the base sheet and integrally bondable to the material to be corrected. The base sheet is perforated or serrated between coatings to facilitate alignment of the indicia with a coating.

The present invention relates to correction materials specifically adapted for correcting visual errors of indicia and the like, and in particular to material for use in facilitating the correction of typewritten errors.

The correction of typewritten errors is a costly and time consuming operation, which greatly increases the cost of stenographic transcriptions of material. Various types of correction material have been previously produced for masking incorrect typewritten material while the document being typed is still in the typewriter. These correction materials are positioned over the error which had been erroneously struck. A further striking of the same key on the correction material causes a release coating to be transferred from the correction material to the typewritten sheet for masking the error. After the correction has been made, it becomes possible to insert the proper indicia.

The present invention overcomes disadvantages inherent in the prior correction material. One of the difficulties heretofore present was that it was often ditficult to properly align the correction material and the typewriter with the previously struck error if the copy was removed from the typewriter and then reinserted. This difiiculty is overcome by providing a transparent peripheral border on the correction material.

Further, in the past one form of the correction material being transferred was powdery, and particles could be brushed away allowing the erroneously struck indicia to blend through the correction. Another type of correction material employed a release coating provided for causing all of the correction material to come off of its base sheet, thereby resulting in a visible glazed surface, which served to point out the location of the corrected mistake because it did not blend with the strata of the typewritten sheet so that the correction became obvious and less desirable than is possible according to the present invention.

The present invention overcomes this disadvantage by providing coatings having a blend of color that is similar to the hue of the typewritten sheet and the adhesive bond on top of this coating is of a clear non-color agent which does not change the blend of color feature and in addition provides a firm bond on the corrected indicia.

The concept of this invention features the use of a plurality of coatings on a base sheet which are of a generally rectangular shape, and which are closely spaced from each other. Weakening lines may be provided between the coatings so that the base sheet may be separated into a plurality of correction elements. Since the base sheet is of a light-transmitting and substantially transparent material, there will result for each of the correction elements a base sheet having an opaque coating with a transparent periphery.

Various types of means may be used to separate the base sheet into a plurality of correction elements, and these may be by way of score lines, serrations, or perforations, as may be desired.

Still further objects and features of this invention reside in the provision of a correction material adapted to enable an operator to effect a simple and speedy correction of an error, which is permanent in nature and which is especially adapted to receive correct indicia because the surface thereof is irregular and tends to blend with the strata of the typewritten sheet.

Still another object of the present invention resides in the provision of a correction material adapted to mask an erroneous impression by providing a coating having an irregular surface that will blend with the strata of the typewritten sheet.

These, together with the various ancillary objects and features of the present invention, which will become apparent as the following description proceeds, are attained by this correction material having visual aligning means, a preferred embodiment of which is illustrated in the accompanying drawing, by way of example only, wherein:

FIG. 1 is a plan view of a portion of the correction material in accordance with the concepts of the present invention, with portions being broken away to illustrate details of the invention;

FIG. 2 is an enlarged sectional detail view taken along the plane of line 22 in FIG. 1;

FIG. 3 is a plan view showing the manner in which the correction material is used;

FIG. 4 is a sectional view illustrating the manner in which the coating of the correction material adheres in part to the typewritten sheet being corrected; and,

FIG. 5 is a view similar to FIG. 3, but illustrating the manner in which one of the correction elements may be used separately.

With continuing reference to the accompanying drawing, wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 is used to generally designate the correction material which includes a base sheet 12 of any suitable flexible or substantially flexible material, and which is substantially transparent in nature. The base sheet may be selected from such material as lightweight paper, glasine, onion skin paper, or any of the various translucent or transparent plastic film material, which may be fabricated in the form of a relatively thin film. This base sheet may be provided with a suitable adhesive coating or glazed to make a plurality of coatings 14 adhere thereto. The coatings 14 are preferably in the form of rectangular shapes or the like. These coatings are of a composition selected to blend with the generally white color of the typewriter paper, but it is to be understood that various types of pigmented coatings may be provided having any desired color. The coatings 14 are arranged adjacent to each other in closely spaced relationship so as to form transparent alignment strips 16 therebetween.

An adhesive pressure-release coating 18 is provided for bonding with the typewritten sheet 20 having the indicia thereon to be corrected. This adhesive coating is such that it will bond with the paper of the typewritten sheet 20 in sufficient manner that when, as shown in FIG. 4, an impression is struck over the correction material 10, the erroneous indicia 22 will be masked by first a corresponding portion of pressure relese coating 18 adhering thereover and causing the coating 14a to be transferred. By virtue of this, an additional transparent surface is created thereby creating greater visual aid to align the correction material over subsequent incorrect indicia.

In FIG. 4 there is shown a modified form of the invention wherein the bond between coating 14 and sheet is so strong as to cause the fracturing of the coating 14 so that a portion 14b remainson the base sheet 10. By virtue of this, the surface of the portion 14a has a relatively coarse or rough texture approximating very closely the general texture of the woven high grade typewriter paper and thus a unique bleeding with the paper is achieved, which is also more receptive to ink when a correct indicia is struck thereover than is possible from a highly glazed fully transferred material.

In use, and with the typewritten sheet having a mispelling of a word such as third, in this case the letters d and r, the correction material is carefully placed with the strip 16 in alignment with the line immediately therebelow. This permits viewing of the line immediately below the line to be corrected by the operator which is necessary for adjustment and alignment of the typewriter with the word to be corrected. Thereafter, the correct letters r and d in proper order are struck.

The operator can also use a stylus or similar blunt instrument to reverse the coating over the incorrect indicia thereby blending out the error. After removing the correction material, proper alignment of the typewriter is made to insert the correct indicia, that is to say, under this invention you need not align the typewriter to strike over the incorrect indicia.

As shown in FIG. 5, only a section of the typewritten correction material need be used after the correction material has been separated into a plurality of sections. This is achieved by aligning the peripheral transparent portion of the sections formed by tearing the correction elements individually from the correction material along serrations 30, score lines 32, or perforations 34, as may be desired, and the erroneous indicia may thereafter be corrected in much the same manner as heretofore described.

A latitude of modification, substitution, and change is '4 intended in the foregoing disclosure, and in some instances, some features of the present invention may be employed without a corresponding use of other features.

We claim:

1. A correction material comprising a transparent base sheet, a plurality of closely spaced rectangular coatings on said base sheet, said coatings being at least partially pressure releasable, a weakening means between said coatings for facilitating separation of said base sheet into a plurality of correction elements each with a peripheral transparent portion for facilitating registry with indicia to be masked, adhesive protective release means on said coatings for bonding with a base having indicia thereon to be corrected with the adhesion of said coatings with said base sheet and said base being stronger than the cohesive tensile strength of said coatings so that said coatings are frangible and only a portion is transferable from said base sheet to form a masking area having a rough texture approximating the texture of paper and adaptable to receive pigmented impressions.

2. A correction material according to claim 1, wherein said weakening means comprises score lines.

3. A correction material according to claim 1, wherein said weakening means comprises perforations.

4. A correction material according to claim 1, wherein said weakening means comprises serrations.
